Boone, Crustacea, Cruises of "Eagle" and ''Ara," 1921-28 127 



Kange : Bathypelagic in the Atlantic, off Newfoundland southward 

 to the Sargasso Sea, also off Ireland, the Azores; Mediterranean Sea. 

 Color: In life this species is spectrum red with bright orange 

 markings on the appendages ; the setae are golden yellow. 



Discussion : The single specimen of S. grandis taken by the "Ara" 

 fully agrees with Dr. Hansen 's exquisite drawings of the species which 

 so thoroughly illustrate the essential anatomy of the species.

Family: LUCIFERIDAE. 



Subfamily : Luciferinae. 



Genus : LUCIFER J. V. Thompson. 

 Lucifer orientalls H. J. Hansen. 



Type: Dr. Hansen founded this species on an extensive series of 

 specimens of both sexes, taken by the "Siboga" in the Indo-Pacific, 

 and deposited at the Leyden Museum. 



Distribution : Known from the Indian and Pacific Oceans. 



Material examined: A single adult male, found in a bottle of 

 plankton, taken by the "Ara" seven miles off Cape Malo, Panama, 

 dredge down 300 fms., March 30, 1926. 



Discussion : This specimen is of genuine interest because it estab- 

 lishes the presence of Hansen 's species in the tropical American Pacific 

 as well as in the Indo Pacific. The figures given by Hansen for his 

 type apply equally to the present specimen.
